ful Improvements in Cumulative Books, of

which the following is a specification, the same being a division ofapplication Serial No. 444,037, nieu July i7, 190s.

This invention is intended particularly for use in the Vbinding ofencyclopedias or other records of current events, or informa tion whichit is desirable to supplement from time to time by means of printedinserts containing currentY news, i'evised records or other informationrequired to keep the bookV up to date withoutcthe necessity forpublishing separate supplementary volumes, which are inconvenient forreference and wasteful of space and disturb library arrangements.

The present invention relates particularly to the method of binding theoriginal volume in such a manner that inserts can'be added from time to'time without distorting the shape or arrangement of the original volumewhich is originally bound in such manner as to be of equal thicknessfrom back to edge, like library books of the ordinary character, inwhich respect it differs radically from ordinary scrap books or similarbooks having stubs orfilling pieces bound therein, which materiallythicken the back of the book and render it unfit for use as a librarybook.

The invention further `consists in the means provided for securing theinserts inV such manner that the purchaser of the book can readily applythem without difficulty and in a perfect manner, so that the book willnot be disgured when the insertions are made.

The invention consists in the features of construction and combinationof parts hereinafter described and claimed. Y

In the drawings, Figure 1 is a perspective view of the book laid open,with the temporary leaves in place; Fig. 2 a similar view showing thetemporary leaves removed in preparation for applying the inserts; Fig. 3a view showing the temporary leaves partially torn away; and Figs. 4 and5 perspective views showing two styles of inserts. lThe book comprises avplurality of permanent printed leaves 6, of the usual character,

bound together in the form of an ordinary library book. At suitablepoints the book is interleaved with tem orary leaves 7 and S arranged inpairs, whic i leaves are adapted to be torn away along weakened tearinglines 9 and 10Vto leave permanent stub portions 11 and 12, one of saidstub portions being of greater width than the other to provide aprojecting edge adapted to have the insert pasted thereon, and the otherstub portion serving to compensate -for the extra thickness of paper atthe point where the insert is pasted.,

The inserts intended for the book above described are preferably of theform shown in Figs. 4 and 5. Fig. 4 shows an insert consisting of a mainleaf 13 and a fly leaf 14 pasted onto the main leal' near its inneredge, leaving a pasting edge 15 of single thickness to be pasted onto.the projecting portion of the wider stub in position to bring the inneredge of the insert in contact with or just outside of the outer edge ofthe narrow stub. In Fig. 5 is shown an insert having a body portion 16of double thickness, and a pasting edge 17 of single thickness.These'forms of insert can be used indiscriminately in the same book.Where the volume of inserted matter is small and can be printed on oneor two pages, it is desirable to use an insert of the form shown in Fig.5, but where three or four pages are required the insert of Fig. 4,consisting of a main leaf and a fly leaf, will be found more desirable.

The book, when. originally published, will be of full size and standardshape, the presence of the temporary leaves serving to give the book auniform thickness throughout, and this form of book will be sold to thepurchaser and installed in his library. Thera after, when inserts areprinted and published from time to time, they can be applied withoutthickening thepbook or distorting it in Aany way. In making theinsertions, a pair of temporary leaves will be torn out, leaving stubs,one projecting beyond the other suiiiciently to afford a pastingsurface. On the pasting surface so afforded the inner or thin edge ofthe insert is pasted, and this edge, being of single thickness, inconjunction with the stub portion to which it is pasted will give adouble thickness at the pasting point, which double thickness, at thepoint of insertion, will be uniform throughout the entire book, so thatwhen the insert is applied l the book Will be restored to its originalthickness, and the reduction in thickness ol the book, occasioned by theremoval of the temporary leaves, Will be fully compensated for.

The method ol forming the temporary leaves in pairs of single thicknessis one which in ncwise interferes with the binding of the book andpermits ordinary paper stock to be used l'or the temporar leaves whichcan be weakened along the intended tearing line in any suitable manner,as by means ol cuts or perforations, although it is not intended tolimit the invention to a weakened tearing line, since a similar resultcould be obtained if the tearing line Were merely indicated by aprinted. line, permitting the user to remove the intended portion bymeans oll a straight edge or ruler.

In speaking` ol temporary leaves, it is not intended to limit theinvention strictly to the use of blank leaves, since, obviously, suchtemporary leaves might have mattei' printed thereon; and it will beunderstood that such language refers to any leaves, blank or printed,Which are bound into the book, with the understanding or intention thatparts of such leaves may be removed, along an indicated tearing line, atsome subsequent time, il desired, to make room for inserts. i

l/Vhat l regard as new and desire to secure i by Letters Patent is: l

l l l l. A book, interleaved, at the points intended to receive inserts,With leaves in pairs,

each el' said leaves having, near its inner edge, a tearing linedividing the leall into an inner permanent stub portion and an outertemporary portion, one ol' the stub portions projecting beyond theother, in combination With an insert having a thickness equal to thecombined thickness olA the two stub portions, save only at its inneredge, said edge being oi' the thickness ol' one ol' the stub portions,the insert being o` a size to bring its Outer edges into register withthe permanent leaves ol the book when the inner edge ol' the insert ispasted to the projecting stub portion, substantially as d escribed.

2. A book, interleaved, at the points intended to receive inserts, withleaves in pairs, each ol.l said leaves having, near its inner edge, aweakened tearing line dividing the leall into an inner permanent stubportion and an. cuter temporary portion, one el' the stub portionsprojecting beyond the other, in combination with an insert having athickness equal to the combined thickness ol` the two stub portions,save only at the inner edge, said edge being ol' the thickness ol' oneof the stub portions, the insert being ol' a size to bring its outeredges into register with the permanent leaves ci' the book when theinner edge oll the insert is pasted to the projecting stub portion,substantially as described.
